+LIFO removal
+============
+
+The *Last In, First Out* (LIFO) removal strategy picks the **newest** products on-hand, based on the
+date they entered a warehouse's stock.
+
+Every time an order is placed for products using the :abbr:`LIFO (Last In, First Out)` strategy, a
+transfer is created for the lot/serial number that has most recently entered the stock (the **last**
+lot/serial number that entered the warehouse's inventory).
+
+.. seealso::
+   :doc:`About removal strategies <removal>`
+
+.. warning::
+   In many countries, the :abbr:`LIFO (Last In, First Out)` removal strategy is banned, since it can
+   potentially result in old, expired, or obsolete products being delivered to customers.
+
+Consider the following example, with the product, `Cinder Block`, which is tracked :guilabel:`By
+Lots` in the :guilabel:`Inventory` tab of the product form. The :guilabel:`Force Removal Strategy`
+for the cinder block's product category is set to :guilabel:`Last In, First Out (LIFO)`.
+
+.. seealso::
+   - :ref:`Set up force removal strategy <inventory/warehouses_storage/removal-config>`
+   - :ref:`Enable lots tracking <inventory/warehouses_storage/lots-setup>`
+   - :ref:`Check arrival date <inventory/warehouses_storage/arrival_date>`
+
+The following table represents the cinder blocks in stock, and their various lot number details.

+     - June 3
+     - June 6
+
+To see the removal strategy in action, create a :ref:`delivery order <inventory/delivery/one-step>`
+for seven cinder blocks by navigating to the :menuselection:`Sales app` and creating a new
+quotation.

+numbers are using the :abbr:`LIFO (Last In, First Out)` removal strategy.
+
+To view the detailed pickings, click the :guilabel:`⦙≣ (bulleted list)` icon, located on the
+far-right of the cinder block's product line in the :guilabel:`Operations` tab of the delivery
+order. Doing so opens the :guilabel:`Open: Stock move` pop-up window.
+
+In the :guilabel:`Open: Stock move` pop-up window, the :guilabel:`Pick from` field displays where
+the quantities to fulfill the :guilabel:`Demand` are picked from. Since the order demanded seven
+cinder blocks, the newest cinder blocks from `LOT3` are selected, using the :abbr:`LIFO (Last In,
+First Out)` removal strategy.
